Robotics teams can now label training video at roughly 1/125th the cost of GPT-6 Astra using Nvidia's open-source Flora.

Key points

• Nvidia's open-source Flora labels an hour of robot video for 72 cents, versus $88 with GPT-6 Astra. source ↗
• Flora scores slightly higher on labeling quality than GPT-6 Astra despite costing far less. source ↗
• The system is built on three fine-tuned Qwen3.5 models. source ↗
• Flora catches errors in robot actions more reliably than rivals but sometimes falls short on descriptive accuracy. source ↗
• Nvidia is positioning Flora as part of a broader strategy to control the robotics value chain. source ↗

Practical applications

• Robotics teams paying for GPT-6 Astra labeling can benchmark Flora on their own footage to verify the 72-cents-per-hour cost and error-detection quality before switching.
• Because Flora is open-source, builders can self-host and adapt its Qwen3.5-based models instead of sending proprietary robot footage to a closed API.
• Teams whose tasks depend on rich scene descriptions should test whether Flora's weaker descriptive accuracy hurts their downstream training before adopting it.

Context

Robot learning depends on large volumes of labeled video showing actions and their outcomes, and having frontier commercial models do that annotation is expensive. Flora is Nvidia's open-source labeling pipeline, built on three fine-tuned Qwen3.5 models, aimed at cutting that annotation cost. The release fits Nvidia's wider push to supply tools and hardware across the entire robotics stack.

What to watch

• Independent replication of the 125x cost and quality claims on datasets outside Nvidia's control would confirm or deflate the launch numbers.
• Adoption by robotics labs beyond Nvidia's own ecosystem will show whether Flora becomes a standard part of the robot data stack.
